MOLDING RING.

Application filed February 26, 19537. Eerial No. M15453.

This invention relates to a molding ring for use in connection withBabbittbearing pouring.

it, very common form of ring employed for this purpose in machine shopsand garages at the present time, is one which made up oi wooden hall.sections suitablyconnected together to operate as enclosures for theliiearingi'; while the Babbitt lining is be ing poured.

it is of course well known that the life of these ring sections iscomparatively short, in fact, they are ordinarily used only two or threetimes when it becomes necessary to throw them away and substitute newones. This is objectionable in that it requires considerable time in thecutting of new ring sections T propose to substitute a metallic moldingring enclosing structure which will aid in the pouring; and will preventleakage of the molten babbitt. incidentally, the objection to theordinary metallicclosure, is that it does not provide snug contact withthe end oi the sections of the bearing. in most instances, the ends ofthe respective sections do not come together in a flush manner.Consequently, it becomes dillicult to term a tight contact between theclosure and the sections oi the hearing. The result, is lealrage of themolten Babbitt.

it follows that the principal objecthere is to provide a sectionalmetallic closure wherein an adjustable filler is provided so that anetlicient closure may be had at all times regardless of theirregularities and re lationship of the ends of the bearing section.

Briefly, the improved structure comprises a. closure ring which iscomposed of hingedly connected halt sections, one of the sections beingsolid or of one-piece construction, and

the other section being composed of two parts, the inner one of whichconstitutes a socalled filler, and which is adjustable toward and fromthe adjacent section of the bearing.

The particular details and advantages will become more readily apparentfrom the tollowing description and drawings,

in the accompanying drawings Figure l is an end elevation of aconnecting rod including stationary bearing sections and removable capshowing the improved closure associated with each part.

lTig. 2 is a side view of the same.

ig. 3 is a detail elevational view of the follower and filler nieniber.

d? 4; is a tra nnentary detail sectional view of a portion of the partrein'esented in Fig. 3.

Fig. 5 is a cross section taken approximately upon the plane of line 5-5of Fig. 3.

Tn. the drawings, the reference character 1 designates a portion of aconnecting rod provided with a head lforining one section of thehearing. The conil ileniental cap is represented by the referencecharacter 3 and as customary, this is bolted in place. As before pointedout, the average cap does not accurately match the bearing section 2with which it is intended to cooperate. The result is that one or bothends oi the cap usually terminate short of the end of the section 2 orextend beyond it. In either case, this produces an irregularity which,when pouring a Babbitt bearing, makes it diilicult to provide aneflicient closure between the Babbitt closing ring in the sections ofthe bearing.

Ubviously it a tight closure is not pres ent, the molten babbitt willleak out. lit follows that the improved closure ring which T haveprovided overcomes this in the following manner,

The closure ring or molding ring is designated by the referencecharacter 4;, and as previously indicated, it is composed of two hallsections. The solid halt section is represented at 5. The coinplenientalsection however, is composed of two parts 6 and 7 which, when in contactwith each other, are of a combined thickness equal to the thickness ofthe section 5 (see Fig. 2). Plates 8 are fastened to the left hand endsof the parts 5 and 6 and these plates are hingedly connected together asat 9, allowing the parts oi the ring to be swung apart to fit over theshaft. The opposite ends of the parts 5 and 6 are provided withbifurcated lugs 10 and 11 with which the retaining bolt 12 and wing nut13 cooperates in an obvious manner.

The part 7 is oi. semi-circular configuration as represented in Fig. 3,and is connected to the part 6 through the medium 0t linger bolts 14.This is accomplished as better represented in Fig, l, wherein it will beseen that on one side and at circuinterentially spaced points, this part7 is formed with recesses into which rectangular plates 15 are lOll rot

end of the bearing cap 3.

fitted and held by retaining screws 16. The bolt'l l is swivellyconnected with the plate as at 17. It follows that by rotating the bolt,this part 7 may be moved toward or 7 from the part 6 in order to permitit to be brought into contact with the bearing section 3 as shown inFig. 2.

At this time, I would direct the "fact that the opposite ends of theparts 7 are recessed on one side for reception of removable blocks 18held in place by removable headed retaining pins 19. The pins extendthrough bores and also through rounded lugs 20 carried by the blocks asshown plainly in Figs. 3 and 5.

From the foregoing description, it is obvious that the parts of themolding ring may be swung apart to fit around the shaft and then thesection 5 can be swung up against and in tight abutting contact with thebearing section 2 as shown in Fig. 2. Assuming however, that the bearingcap 3 is slightly shorter than the bearing section 2, it will be seenthat an irregular surface will be present. However, by making a separateadjustment of the adjustable part 7 of the upperhalt section of thering, this part can be brought into contact with the Thus the parts 5and 7 together will operate as an eilicient closure to permit pouringot' the babbitt while preventing leakage.

In some instances, bearing caps are provided on the ends withprojections or flanges, and it is for this reason that I have provided aremovable block 18, which, when taken out, provide clearance spaces toacattention to commodate such projections.

It is thought that by considering the de scription in connection withthe drawings, it will be seen that Ihave evolved and producedexceptionally novel molding ring structures for the purpose specified,which issuperior to the ordinary wooden rings nesaeeo employed and whichis ellicient, in that it can be accurately adjusted for forming a tightclosure.

Persons skilled in the art to which the invention relates willundoubtedly be able to understand the construction and method of use, aswell as the advantages a tter reading the foregoing description.'lliereihn'e, a more lengthy description is thought unnecessary.

Vhile the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes coming within thefield of invention claimed may be resorted to if desired.

Having thus described my invention, what I claim as new is 2- 1. In astructure of the class described, a closure forming and molding ring fora bearing structure comprising an annulus composed of hingedly connectedhalt sections, one half section being in turn composed of relativelystationary and adjustable parts, the adjustable part being movabletoward and from the bearing cap, the parts of said last section being ot a combined thickness equal to the thickness of: the complementalsection.

2. A combined molding and enclosure forming ring for a bearing structureof the class described comprising an annulus composed of a one-piecesen'ii-circular section, and a two-part complemental semiwircularsection, the two-part section embodying a relatively stationary parthingedly connected to said one-piece section, and a relatively movablepart adjustable toward and from the bearing to be treated, bolts carriedby the stationary part and swivelly connected with the movable part, andseparable end blocks fitted in recesses lorniei l in the end portions ofsaid movable part.

In testimony whereof I :nlix my signature.
